I’ve never been happier with a boost/overdrive pedal before. I run a baritone into this, then into a Dark Terror and it tightens up the low end enough to do any flavor of modern metal you can hope for and is voiced perfectly. I also tried the “under-driving” method using the flat-eq setting and that was cool because it tightened everything up without shaving off hardly any low-end. Awesome tool to have on my pedal board. Killed any desire to look elsewhere for a boost/od.
